Optical properties of cobalt ferrite (CoFe2O4)/barium titanate (BaTiO3) nanoparticles are modeled and simulated utilizing density functional theory (DFT) finite element analysis (FEA) intended for various particle sizes. The absorption maxima electronic excitations is red-shifted from 259.51 nm to 315.27 employing quantum mechanical approach 260 280 using analysis, corresponding enlarging sizes...

Multiple-phase nanocomposites filled with carbon nanotubes (CNTs) have been developed for their significant potential in microwave attenuation. The introduction of other phases onto the CNTs to achieve CNT-based heterostructures has been proposed to obtain absorbing materials with enhanced microwave absorption properties and broadband frequency due to their different loss mechanisms. The existe...

The crystal structures of different forms of TiO2 and those of BaTiO3, ZnO, SnO2, WO3, CuO, Fe2O3, Fe3O4, ZrO2 and Al2O3 nanoparticles have been deduced by powder X-ray diffraction. Their optical edges have been obtained by UV-visible diffuse reflectance spectra. The photocatalytic activities of these oxides and also those of SiO2 and SiO2 porous to oxidize iodide ion have been determined and c...

A magnetically controlled elastically driven electroporation phenomenon, or magneto-elasto-electroporation (MEEP), is discovered while studying the interactions between core-shell magnetoelectric nanoparticles (CSMEN) and biological cells in the presence of an a.c. magnetic field. In this paper we report the effect of MEEP observed via a series of in-vitro experiments using core (CoFe2O4)-shell...

We studied various electrical and optical properties of Europium (1 atomic %) incorporated BaTiO3 film on n-Si(100) substrate. The thin film structure was analyzed by X-ray diffraction. Film thickness and optical refractive index were measured with an ellipsometer. P-E hysteresis measurement shows the remnant polarization of 37μC/cm in BaTiO3:Eu film. C-V measurements on the pure BaTiO3 film sh...

Aluminum oxide encapsulated high-permittivity (ε) BaTiO3 and ZrO2 core-shell nanoparticles having variable Al2O3 shell thicknesses were prepared via a layer-by-layer methylaluminoxane coating process. Subsequent chemisorptive activation of the single-site metallocene catalyst [rac-ethylenebisindenyl]zirconium dichloride (EBIZrCl2) on these Al2O3-encapsulated nanoparticles, followed by propylene...
